MultiChain Web Demo Error Problem

Question

Hello. I am new in multichain.

I just finished installing this framework(Multichain Web Demo) with following all the guides provided in the GitHub repo. However, there's something like incomplete process/step. I have an error like this:

Error: -32601 Method not found

Error: -5 Invalid permission

Can anyone share some solutions or idea on how to fix this?

Thank you.

What are you doing when you see this error?

Hello, thanks for replying. Actually, what I'm trying to do is to setup this web demo interface for me to learn the multi chain. I don't why this error messages show up. I try to change the multichain version to see of it's work but the error changes to something else with more detailed. It says that the API that I'm used is not compatible with the Protocol Version. I checked that now my protocol version is 10005. Do you any solutions for this?

Answer 1

Thanks for explaining in the comment. Judging by the protocol version you mentioned, the problem is probably that you're running a very old version of MultiChain which is not supported by the Web Demo. If this is the case please start again with a new chain running on the latest version, 1.0 beta 1.

Hello. Yes, the problem regarding the protocol version is solved when I change to the latest version, 1.0 beta 1. Thank you for that :)

But there are other problems too. In my 'page-permission.php', there is an error like this

Notice: Undefined index: address in /opt/lampp/htdocs/multichain-web-demo-master/page-permissions.php on line 34.

It is like the variable 'address' in that line was never be initialized/have a value. I don't know how to fix this. Appreciate if there are any solutions/idea.

It's just a PHP warning and doesn't do any harm, but we've pushed a fix for it.
